Were it not for advances in bioinformatics, extracting copy number variant data from exome sequencing would remain prohibitively challenging.
若非生物資訊學的進步，從外顯子組定序中提取拷貝數變異數據將仍然具有極高的挑戰性。
#11
The study's findings suggest that exome sequencing-based approaches could serve as a viable first-tier genetic diagnostic test for developmental disorders across Africa.
該研究的發現表明，以全外顯子組定序為基礎的方法，可作為整個非洲地區發育障礙的可行第一線基因診斷測試。

Should these methods gain wider adoption, they would significantly reduce the financial burden associated with separate genomic analyses in regions where healthcare resources are scarce.
倘若這些方法獲得更廣泛的採用，它們將顯著減輕在醫療資源匱乏的地區中，與獨立基因組分析相關的財務負擔。
